The airline has been trying to transform its operations and return to profitability by 2019 as it recovers from two disasters in 2014, when flight MH370 disappeared in what remains a mystery and flight MH17 was shot down over eastern Ukraine.

Sovereign wealth fund Khazanah Nasional Bhd, which took MAB private in 2014, said the government needed to decide on its investment in, and level of support for, the struggling airline.

The fund also said that it was waiting for MAB to present a review of its business strategy.
